How animals sense Earth’s magnetic field is one of biology’s enduring mysteries.
Researchers in Science have now identified superparamagnetic macrophages in the livers of rock pigeons to be crucial for magnetic sensing. The finding uncovers an unexpected role for immune cells in sensory perception and may fundamentally change our understanding of animal navigation.

NEW STUDY - Japan Sees 40-Year Decline in Cavities Without Using Fluoride
“Japan experienced a near-continuous decline in caries among 12-year-olds over approximately 40 years… well below levels historically reported in populations exposed to systemic fluoride through community water fluoridation.
This decline occurred without community water fluoridation and largely before the approval of high-fluoride toothpaste in 2017 and its recommendation for school-aged children in 2023.
Japan represents a rare natural social experiment demonstrating that sustained population-level caries reduction can occur through cumulative non-systemic fluoride pathways.
These findings suggest fluoride-centered frameworks alone may not fully explain long-term population trends and support a broader multicausal approach to caries prevention.”
On Memorial Day, important to remember that Agent Orange—the toxic herbicide used during the Vietnam War—has sickened or killed hundreds of thousands of US veterans and Vietnamese civilians. Monsanto produced the largest amount and the dirtiest—most contaminated by dioxin—version
"If you're not failing, you're not pushing boundaries."
Hear medicine laureate Elizabeth Blackburn speak about the valuable lessons we can learn from failure.
The Brazilian lawsuit comes after the retraction of a decades-old paper that prosecutors say was used by regulatory agencies worldwide to allow registration and sale of glyphosate. They also cite studies showing glyphosate residues in drinking water pose a threat to human health.
Humanity, created by God in all its grandeur, is today facing a pivotal choice: either to construct a new Tower of Babel or to build the city in which God and humanity dwell together. In Jesus Christ, this humanity in its grandeur becomes the Way, the Truth and the Life, opening the path for each of us to grow toward fullness. #MagnificaHumanitas

@ylecun Because they brought everybody amd their grandmother also. I came with nothing and remain thus. Nulla-tenente, and have made no-claims to corporate america. Just a gold rolex is owed. Then, I will go. Else? I will bring the entire italian peninsula and the island cousins also.
